Your version of DS2 is unchanged upon the installation of BW (different directory), so it's actually BW that is v2.3... To continue into Vet, use the BW exe and choose the DS2 map when starting up a new game. Your Inn characters should be there waiting to go into battle with you once again.
PS. It's a little weird having Amren in your party during the opening Vet. NIS... (him in the jail cell with you and his doppleganger outside chatting with Celia about you).
